@pillarama I don't know about FOTA, but I see no reason why it would not work. I guess it depends what you do with it! I like being able to burn bootloader from within arduino ide and not having to swap to avrdudess et al - now I can boot load and program in the same window. I was amazed at how easy it is to install and use. No need for fuse calculators, just choose clock speed, internal or external and brownout and click burn. I do hope to try FOTA in April (real life allowing) and so will comment more then.... Only snag is it dosn;t work with the ardudriod on android, I have contacted the dev of that app and sent the error message but as yet no solution. Maybe it will be possible in the future to do all this from phone and needing PC..... It is very close.
